DETROIT – The all-new 2015 Corvette Z06 is a many absolute prolongation automobile ever from General Motors and one of a few prolongation cars accessible in a United States that delivers some-more than 600 horsepower.

The Z06’s LT4 supercharged 6.2L V-8 engine is SAE-certified during 650 horsepower (485 kW) during 6,400 rpm and 650 lb-ft of torque (881 Nm) during 3,600 rpm.

“The LT4 Small Block sets a new benchmark for energy and torque during GM,” pronounced Steve Kiefer, clamp president, GM Powertrain Engineering. “The engine also puts a new Corvette Z06 on customary with a many absolute supercars charity in America, while delivering opening with exquisite manners that make it suitable for daily driving.”

Compared with other supercar engines, a LT4 is a undoubted fountain of low-end torque, producing 457 lb-ft (619 Nm) usually off idle and 625 lb-ft (847 Nm) by usually 2,800 rpm. The V-12-powered Ferrari F12 Berlinetta, for example, produces about 28 percent reduction torque than a Z06, notwithstanding charity about 12 percent some-more horsepower – and a rise torque isn’t achieved until 6,000 rpm. The LT4 maintains 90 percent of a rise torque, or 592 lb-ft (802 Nm), from 2,500 to 5,400 rpm.

The new LT4 engine eclipses a Porsche 911 Turbo S engine’s rise energy levels by 90 horsepower (67 kW) and 134 lb-ft of torque (182 Nm).

“Torque is a pulling energy of an engine and a LT4’s contentment of it during each rpm in a engine’s speed operation helps a 2015 Corvette Z06 accelerate quicker and respond scarcely instantaneously,” pronounced Jordan Lee, arch operative for Small Block engines. “It’s a really clarification of energy on demand.”

The new Z06 engine produces 40 percent some-more rise torque (180 lb-ft / 244 Nm) than a previous-generation’s 7.0L LS7 engine – and 7.5 percent some-more than a supercharged 2013 Corvette ZR1’s 604 lb-ft (819 Nm). At 3,200 rpm, a new LT4 surpasses a LS7 by 208 lb-ft of torque (252 Nm). On a horsepower side of a graph, a LT4’s 650-hp rating is 29 percent larger than a LS7’s 505 horsepower (376 kW), and 12 horses some-more than a ZR1’s LS9 engine.

“The new LT4 engine builds on a pattern strengths of a prior supercharged engine and leverages a technologies introduced on a Corvette Stingray – approach injection, cylinder deactivation and invariably non-static valve timing – to take Corvette opening to an all-new plateau,” pronounced Lee. “Our new, really compress supercharger also helps a engine make energy some-more quickly, and maybe some-more importantly, it helps furnish some-more torque progressing in a rpm band.”

“It’s also value mentioning that a LT4’s supercar opening numbers are achieved with an engine that is scarcely a same distance as a really compress LT1 engine introduced in a 2014 Corvette Stingray,” Lee said. “The energy firmness of a LT4 creates it one of a smallest and lightest 650-hp engines in a industry.”

LT4 details

The new LT4 engine is formed on a same Gen 5 tiny retard substructure as a Corvette Stingray’s LT1 6.2L naturally aspirated engine, incorporating several singular facilities designed to support a aloft outlay and a larger cylinder pressures combined by forced induction, including:

  • Rotocast A356T6 aluminum cylinder heads that are stronger and hoop feverishness improved than required aluminum heads
  • Lightweight titanium intake valves
  • Machined, fake powder steel steel joining rods for reduced reciprocating mass
  • High 10.0:1 application ratio – for a forced-induction engine – enhances opening and potency and is enabled by approach injection
  • Forged aluminum pistons with unique, stronger structure to safeguard strength underneath high cylinder pressures
  • Stainless steel empty manifolds and an aluminum balancer that are lighter than their LT1 counterparts
  • Standard dry-sump oiling complement with a dual-pressure-control oil pump.

A new 1.7L supercharger spins during adult to 20,000 rpm – 5,000 rpm some-more than a supercharger on a Corvette ZR1’s engine. The rotors are smaller in diameter, that contributes to their higher-rpm capability – and enables them to furnish power-enhancing boost progressing in a rpm band. That boost is achieved some-more well around a some-more approach liberate pier that creates reduction turbulence, shortening feverishness and speeding airflow into a engine.

“The Small Block’s cam-in-block pattern birthright has always enabled really high opening and responsiveness in a small, compress package – an charge amplified by a opening of a new supercharger’s design,” pronounced Lee.

The LT4 is fabricated during a new Performance Build Center during GM’s Bowling Green Assembly Plant and during GM’s Tonawanda engine plant in New York. It is matched with a customary seven-speed primer delivery or an all-new, paddle-shift eight-speed involuntary delivery built in Toledo, Ohio.

Designed to broach change responses on customary with a world’s best dual-clutch transmissions, it is a initial involuntary charity in a Z06. It also creates a Z06 one of a few cars this absolute to offer a choice of a required primer delivery or an eight-speed automatic.

The 2015 Corvette Z06 goes on sale in a fourth entertain of 2014.
